Abstract
The present invention relates to a method for selectively producing ginsenoside Rd, which is originally present in ginseng in a trace amount, from panaxadiol-type saponins of ginseng, and more specifically to a method capable of obtaining a desired target compound, that is, ginsenoside Rd, in high yields, by treating a panaxadiol-type saponin obtained from ginseng, with particular enzymes to structurally convert the saponins.
